手指心率偵測與倒車雷達

Heart Rate Monitor and Parking Radar Experiment 

This experiment will use a photointerrupter, a bandpass filter, and Arduino's ADC to measure heart rate. In addition, we will practice using the ultrasonic distance measurement module and the horn to integrate into a reversing radar.

這次實驗將使用光遮斷器、帶通濾波器與 Arduino 的 ADC，進行心率測量實驗。此外，還要練習使用超音波測距模組與喇叭，整合成一個倒車雷達。
